Nylon Spandex Copper Ion Filament Four-Way Stretch Recovery Seamless Circular Knit combines nylon spandex with copper bearing filament with a Seamless Circular Knit construction. It is aimed at Training Shorts that require abrasion resistance plus a comfortable liner, and the reason is straightforward: antibacterial action plus faster heat transfer away from the skin, so Four-Way Stretch Recovery.

Why this construction works
Because a seamless circular knit is used, the fabric behaves consistently across the roll: tubular production that removes the side seam entirely. That consistency is what lets a factory cut confidently and lets a brand repeat an order a season later with the same result.

Performance features
- Four-Way Stretch Recovery: extends in both directions and returns without bagging, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: antibacterial action plus faster heat transfer away from the skin.
- Construction benefit: tubular production that removes the side seam entirely.
- Consistency: GSM and width tolerance are locked per lot and recorded on the inspection sheet.
- Durability: performance is verified after repeated washing, not only as delivered.
Recommended applications
Used for Training Shorts and for the accessories around them. abrasion resistance plus a comfortable liner is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

Dyeing, finishing and customisation
The fabric can be supplied greige, piece dyed or printed. Add-on finishes are selected after a wash durability trial, because a finish that disappears after five washes is worse than no claim at all.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.
Ordering, sampling and quality control
Minimum trial order is 300 metres per colour and bulk production takes 20-25 days once the approval sample is signed. Documentation includes test reports per lot, OEKO-TEX conformity and full construction sheets.
Roll inspection and packing before shipment
Frequently asked questions
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
